TOY STEill/I SHOVEL.

Application filed July 11, 1925. Serial No. 43,011.

This invention relates to new and useful improvements in toys, and particularly to toys which are built to simulate, as well as to operate, in the manner of the 'full sized machine.

@ne object of the invention is to provide a toy which is built to resemble the ordinary steam shovel, ind which has mechanism for operating the shovel to perform the same motions that the full sized machine performs. Y f

Another object is to provide a device of this character which is simple in construction, easy to operate, and which can be manufactured at a low cost.

Another object is to provide novel mechanism for actuating the shovel through its digging andV lifting movements, and subsequently swinging the same toward one Vside and dumping the contents of the shovel.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings:

Figure 1 is a side elevation of a toy steam shovel made in accordance with the present invention.

Figure 2-is a top plan view of the same.

Figure 3 is a vertical transverse sectional view on the line 3-3 of AFigure 2.

Referring particularly to the accompanying drawings, represents a base which is mounted on the wheels 11. Pivotally mounted on the base, for horizontal swinging movement, is a platform 12, and mounted on the forward end of this platform are the uprights 13, the upper portions of which converge and pivotally support therebetween the walking-beam 14C. The base is formed of sheet metal and has the downturned side portions 15, in which are supported theV ends of the axles 16, on which the before-mentioned wheels 11 aremounted. Secured to the horizontal portion of the base 10, and at the forward end thereof, is an elevated table 18, through which the pivot 19 of the platform is disposed, and on which said platform turns. Properly secured to the upper face of the platform 12 are the angular U-shaped members 20 and 20', in the vertical arms of which are supported the ends of the shafts 2l and 22. Formed in the platform 12, in concentric relation to the pivot 19, is an arcuate slot 23, and secured to the base 10, and extending vertically through said slot, is a post 2l, having a roller 2.5 mounted in its upper end. Formed on one end of the shaft 21 is a crank handle 26, and fixed on the shaft, inwardly of the crank i handle, is a small gear 27, which meshes with a larger gear 28, mounted on the adjacent end of the shaft 22. On the other end of the shaft 22 there is secured a disk wheel 2 to which is eccentrically pivoted one end of a link 30, said link having its other end pivotally connected with the adjacent end of the walking-beam 14. Formed on the inner face of the larger gear 28 is a cam face 31, which is adapted to intermittently engage with the roller 25, whereby to cause the platform l2 to swing on its pivot 19. Disposed beneath the plat'- form 12, and connected at its opposite ends to one side of the platform, and to the opposite side of the,s hase, respectively is a coil spring 32, which. normally urges the platform 12 into central position with respect to the base, but which will permit the platform to swing. .On the other end of the platform 12 is the boiler 10 Pivotally connected to the front end of the platform 12 are they arms 33, the outer ends of which are connected by an upturned bight portion 34, `and engaged on this bight portion is the eye of the lower end of the link 36, which has its upper end pivotally connected to the other end ofthe walkingbeam 14. :i scoop, or bucket 37 is provide-C with a pair of tubular members 38, on its upper side, which receive the arms therethrough, and whereby the bucket is adapted to slide toward and away from the. platform 12. Pivotally connected to the bucket, at one end, and at its other end eccentrically pivoted to the larger gear 28. is a. link 39. which causes the bucket to slide back and forth on the arms 33, as the gear 28 revolves. At the same time the link 30 is reciprocated by the disk wheel 29, to cause the walking-beam to be rocked, with the result that the arms 33 will be elevated and depressed in succession, to raise and lower the bucket. Pivotally mounted on the lower side of the bucket or scoop is a dumping door 10, and connected to the door, and to the base 10, is a cord 41. On the bucket and door are connected the ends of the coil spring l2, which yieldably maintains the door in closed position.

Upon rotating the crank handle the gears 2T and Q8 will rotate the shaft 22, causing the link 30 to rock the Walking-beam, which in turn raises and lowers the arms 33, through the medium of the link 35. At the same time, the link 39 causes the bucket to slide back and forth on the arms 33. It will be noted that when the arms 33 are being lowered the bucket is being projected outwardly on the arms so that said bucket or stoop will dig into a pile ot sand, filling the bucket. Further rotation of the shatt 22 causes the Walkingeam to elevate the arms 33. lifting the bucket with its load et' sand. .fit this time the cam face 3l Will hare engaged with the roller with the result that the platform l2 will be swung around on its pivot 19, carrying the elevated arms 33 and bucket 3T `with it` until the cord ell becomes taut, When the door 40 will be swung downwardly to let the sand fall from the bucket. Immediatelyv that the cam tace 3l passes from the roller 25, the spring. which was placed under tension by the swinging ot the platt'orm toward the side, Will restore the platform to its normal central position fith respe-.t to the base l0. and the cord to slack condition, permitting the spring 42 to close the door 40, ready for another operation.

has. upon continuouslyT rotating the crank handle Q6. the bucket Will be projected forwardly to scoop sand, be elevated with its load, be swung to one side and its contents or load dumped, after which the parts Will be brought to their normal position by the spring 32. Taese phases ot the operation oi the toy will continue as long as the crank is turned.

That is claimed is:

l. A toy diggin# machine including a base, a laterall7 swingable platform on the base, an upright on the base, a cam means on the platform, and means for rotating the cam means into engagement with the upright whereby to cause the lateral swinging otl the platform.

2. toy digging machine including a base, a laterally svvingable plattorni mounted on the base, an upright on the base.y a cam on the platform engaged With the upright, means for rotating the cam to cause the lateral swinging of the platform, and means tor restoring the plat-form to normal position.

ging machine including a swingable platform on the l it on the base. a rotatable cam on the pli,` n ing with the upright. spring means for urjs 'i g the platform in one direction, and means tor rotating the cam to turn the platform in the other direction.

i. toy digging machine including a hase, a laterally7 swingable platform on the base and having an opening therein. an upright on the base extending through said opening'. a gear on the platform7 a cam on the gear engaging the upright, means i'or rotating the gear whereby to turn the platform in one direction. and a spring connected to the platform and base t'or returning the platform to normal position.

A. toy digging machine including a base. a laterall)1 swingable plattorm mounted on the hase and having a slot concentric Wit-h the pivot ot' the glatter-xn. an upright mounted on the base and projecting upwardly through said slot, a gear mounted en the platt'orm a cam on one face ot' the gear bearing against said upright. a second gear meshing with the first gear. means tor rotating the second gear, to cause the platform to swing in one direction. and a spring connected to the platform and hase 'tor swinging the platform in the other direction.

In testimony whereof, l affix my signature.

FRED C. EASTHAM.
